Embodiment 1

[0025] like figure 1 A device for layer-by-layer printing of three-dimensional products is shown, including a casting mold platform 1, a powder spreading device 3, a printing head 6 and a frame platform 2, the casting mold platform 1 is set on the frame platform 2, and the frame platform 2 is on the casting mold platform. One end of 1 is provided with a powder spreading device 3, and the rack platform 2 is provided with a sliding guide rail 4 at the other end opposite to the powder spreading device 3. The sliding guide rail 4 is provided with a printing head 6 through a sliding fixed seat 5. A feeding port 7 is provided at the position, and a discharging port 8 is provided at the lower end position of the powder spreading device 3 which is matched with the feeding port 7 .

[0026] In this embodiment, the mold platform 1 can move vertically up and down, the powder spreading device 3 drives the sliding guide 4 to move along the Y-axis direction through the motor 9, and the powd...

Embodiment 2

[0028] like figure 2 and image 3 A method for using a device for layer-by-layer printing of a three-dimensional product is shown, including the following contents:

[0029] At the beginning of printing, the powder spreading device 3 filled with particulate material is firstly located, and the powder spreading device 3 is located at the initial edge of the mold platform 1;

[0030] Open the discharge port 8 and lay a layer of granular material;

[0031] At the same time, the powder spreading device 3 is driven to the opposite edge of the mould platform 1 at a constant speed, so that the mould platform 1 is covered by a uniform layer of granular material;

[0032] After the material is conveyed, the powder spreading device 3 is reset, and the feeding port 7 is opened for charging;

[0033] The print head 6 moves to a prescribed area on the mold platform 1 along a prescribed path through the movement of the sliding guide 4 , sprays the adhesive, and then returns to the origi...

Abstract

The invention discloses a device for printing a three-dimensional product layer by layer. The device comprises a casting mould platform, a powder paving device, a printing head and a rack platform, wherein the casting mould platform is arranged on the rack platform; the powder paving device is arranged at one end of the casting mould platform by the rack platform; a sliding guide rail is arranged at the other end relative to the powder paving device by the rack platform; the printing head is arranged on the sliding guide rail through a sliding fixing seat; a feeding hole is formed in the upper end of the powder paving device; and a discharging hole matched with the feeding hole is formed in the lower end of the powder paving device. The device is simple and reasonable in structure, automatic powder paving and printing are finished through movement of the casting mould platform, the powder paving device and the printing head, the entire process is automatic operation, the working efficiency is high, powder paving is uniform, the entire process is excellent in continuity, and a formed product is high in quality.

Description

technical field [0001] The invention relates to the technical field of three-dimensional product printing, in particular to a device for layer-by-layer printing of three-dimensional products. Background technique [0002] 3D printer is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. At present, traditional 3D printers on the market are realized by layered construction. The powder spreading tank firstly lays a thin layer of powder material on the mold platform evenly. Then, the printing head sprays the binder according to the model layered structure calculated by the program, and then the binder is dried by ultraviolet rays to achieve the purpose of "powder and ink" combination, and then layered printing is carried out, and finally the mold is formed. 3D printing enables rapid prototyping from CAD models to finished products, and is a rapid prototyping technology that is faster and easier to implement than other rapid prototy...
